Approval and Promulgation of Implementation Plans South Carolina: Approval of Revisions to the 1-Hour Ozone Maintenance State Implementation Plan for the Cherokee County

EPA is approving revisions to the Cherokee County 1-hour ozone maintenance area portion of the South Carolina Air Quality State Implementation Plan (SIP), submitted by the South Carolina Department of Health and Environmental Control (SC DHEC) on January 31, 2002. This SIP revision satisfies the requirement of section 175A(b) of the Clean Air Act (CAA) for the second 10-year update for the Cherokee County maintenance plan. Additionally, this submittal explicitly identifies the motor vehicle emission budgets (`budgets') for oxides of nitrogen (NO<INF>X</INF>) and volatile organic compounds (VOC). In this action, EPA is also approving and finding adequate Cherokee County's `budgets' for NO<INF>X</INF> and VOC supplied in this updated maintenance plan. These budgets, identified for the year 2012, will be used for the purposes of conducting transportation conformity analyses for Cherokee County, in accordance with the requirements of the CAA amendments of 1990 and the Transportation Conformity rule.
